What Is This Tour All About?

This boat trip is designed to showcase the natural beauty along Portugal’s Arrábida coast, starting from the tranquil harbor of Sesimbra. The focus is on exploring the coast’s caves, hidden bays, and geological features formed by marine erosion. The entire experience lasts about 2.5 hours, making it a manageable half-day activity that can fit into most itineraries.

The journey begins with a friendly check-in at Bolhas Tours’ Marine Center, located right in Sesimbra’s harbor. Here, you’ll receive a safety briefing and some background about what lies ahead. From there, the boat departs into the calm, protected waters—sweet relief from the sometimes choppy Atlantic.

Exploring the Caves and Geological Marvels

One of the main highlights is the chance to view limestone caves that characterise the Arrábida coastline. You’ll visit the Tamboril Grotto, noted for its spectacular lighting and crystal-clear waters—great for photos or just soaking in the scenery. Next, you’ll come face-to-face with the Frade Grotto, one of the biggest cave systems in the area, which is often a crowd favorite for its impressive size.

Other geological formations like the Mesas—flat-topped structures shaped by marine erosion—are fascinating to see close-up. As the boat cruises along, guides tend to share stories about the area’s geological history, adding context to these natural sculptures.

In addition, you’ll visit Sesimbra’s own monumental caves, including the Arco da Pombeira Grotto. This spot offers a dramatic view, with a large arch-shaped formation that frames the sea. Bifa, another geological feature, is known for expelling water like a geyser, providing a dynamic spectacle that keeps the tour lively.

Bays, Beaches, and Snorkeling

The cruise isn’t just about caves — you’ll also explore hidden bays and beaches that are often unreachable by land. Ribeiro do Cavalo Beach, for instance, is a small, protected cove that looks almost untouched, perfect for a quick stop and photo.

Most travelers seem to appreciate the opportunity to swim or snorkel in a pristine marine protected area. You’ll be offered snorkel gear and given some time in a quiet cove, where water clarity can vary depending on weather conditions. Some reviews, like a recent one from Denmark, mention that the snorkel stop can sometimes be disappointing if water is murky or visibility is poor—so don’t expect perfect conditions every time.

You’ll love the calm waters of the marine park, which are shielded from waves and north winds by the surrounding mountains. It’s a relaxing, gentle environment ideal for those who want to dip their toes in or explore underwater life without the worry of strong currents.

The Experience of the Guides and the Group

Guides seem to be a standout part of this tour. Multiple reviews praise the knowledgeable guides like Mariana and Tiago, who go out of their way to make sure everyone understands the area’s geology and stories. One traveler from Germany described their guide as “super friendly” and the experience as “super well organized.”

The boat itself is described as comfortable, with some reviews noting that the image-provided boats tend to look different in real life—less glamorous perhaps, but functional. Group sizes are generally small, with a maximum of 8, though some reviews have slightly exceeded that, which could affect the intimacy and comfort.

The multilingual guides who speak English, French, Portuguese, and Spanish make it easier for international visitors to enjoy the tour without language barriers.
